Rural microgrid planning considering ice-plate sliding ice storage systems

The ice storage system utilizes ice as an energy storage medium, leveraging the significant latent heat during the phase transition of water. It produces and stores ice during off-peak electricity hours and melts the ice to release cooling during peak electricity hours to meet the cooling demand of rural cold storage facilities, thus achieving the effect of peak shaving and valley filling for the power grid. A linear model of the sliding ice-on-coil ice storage system considering the phase transition conditions, as well as a cold storage cooling load model, have been established. By coupling with the microgrid power system, the operational constraints and coordinated control of distributed power generation, power storage and ice storage are considered, and the superiority of the ice storage system is demonstrated by comparing with the conventional cooling system.
